, j The present wallstructure is particularly de- "signed for use with tubes in forming such wall structures as are commonly called water walls. In many furnace structures some'walls' at least are formed by arranginga. series of tubes in the general plane of the wall and facing these tubes with blocks, metal blocks being commonly used. 'It is desirable to maintain the tubes in substantially aconstant" relation, usually paralleland to at .the same time, thoroughly secure the different blocks in contact with the tubes so that there may be a ready heat exchange between the blocks and tubes. The present invention accomplishes these desirable features in a simple and efiicient manner. Features and'details of the invention will appear from thespecification and .claims.

Preferred embodiments of the invention are illustrated in the accompanying drawings as folows:-'-

1 marks the tubes. These are usually in parallel relation and usually vertical, or at least may be upright. 2 marks the blocks shown in Figs. 1 to 5. Each of these blocks is provided with a pair of grooves 3, the grooves forming seats for the tubes. Each block has a threaded opening 4 receiving a screw 5 extending from aclamping plate 6, the clamping plate resting onadjacent tubes. The wall is arranged with joints ,1, these joints .beingb'etween the tubes and are preferablystag gered, or off-set, as clearlyindicated'in Fig.2. In this way each pair of adjacent tubes is'seated in some grooves associated in the same blocks, so that the tubes of each pair a're'tied together in each alternate row of blocks. The association of a plurality of grooves in each block is 'efiective in tying the tubes in proper relation, particularly where the blocks are arranged in staggered relation so that there is a single block bridging and embracing each pair of tubes.

'Pa., a corporation 1932, Serial No. 638,065 I 7 (ol. 122-,-s) r This structure has many advantages over what is more commonly used. In the structures more commonly used the blocks forming thewall have their ends terminating in thefronts of each-pair of tubes; so that as the block is clamped'to its seatthe, sidesurfaces of these blockswhich are under-cut toeng'age the walls of the. tube tend to'spre'ad the tubes, and in order to hold the "tubes and'the wall in shape greater dependence must be given to the shape of the clamps. With the present invention the blocks having the associated tube embracing grooves avoid any tendency to separate the tubes, but on the contrary tie them together. The structure also permits of the use of a wide variety of clamps as the embracing action of the blocks accomplishes some of the functions which are sometimes performed by the clamps.

r o In Figs. 6 and 7' the blocks are similar to those shown in Figs. 4' and 5 except that thereare two openings 8 and 9 instead of the single opening 4' and T-shaped bars) extend entirely across the wall and bolts ll extend through these bars into the screw-threaded openings Band 9 for securing the blocks in place. e

1 In the structure shown in Figs. 8,9, and 10, the" blocks l2 are each provided with three grooves l3, thus engaging three tubes and the joints between the ends are staggered so that they are distributed between the tubes so that a break between any two tubes occurs only inevery third row of blocks. The blocks are provided with screw-threaded openings l4 and clamps l5 are arranged over each tube with relation'to each block. The ends of these clamps are secured to the block by screws I6. J

' Under some conditions it may be desirableto limit the number of tubes which are definitely tied together by. the wall system. This may be accomplished by so forming the wall blocks as to 'form the wall in panels, each panel involving a group of tubes definitely tied and associated to- 'gether, but separated from the adjacent panel.

In Figs. 11 and '12 .onemodification carrying out this structure is shown. A panel ll associates a seriesof tubes. I v s s of normal size embracing a number of tubes,

Some of the blocks I8 may be.

Whereas other blocks l9 supplementing theblocks 18 in width associate the remaining tubes of the panel. By making some of the blocks shorter than others the breaks between the blocks may be staggered so that all thetubes of apanel .may be tied together in the manner heretofore described with. relation to the entire wall. v

In thefmodification shown. in Figs. 13 andl l the panels 20 are formedbyutilizing blocks'2l.

which have a length equal to the width of the panels so that all the tubes of the'group forming the tubes in place are shown, as for instance in Figs. 8 and 13. In Fig. 19 small blocks are interposed between the tubes and the clamping bars as distinguished from the structure shown in Fig. 13.
